Enhanced HKDF-based key derivation with improved security features
- Implemented proper RFC 5869 compliant HKDF key derivation process - Added Perfect Forward Secrecy (PFS) key for enhanced session security - Improved key separation using unique info parameters for each derived key - Enhanced salt size from 32 to 64 bytes for increased entropy - Added comprehensive key validation and error handling - Implemented proper ECDH + HKDF integration following Web Crypto API best practices - Added metadata encryption key for enhanced data protection - Improved compatibility with modern cryptographic standards (RFC 7748, NIST SP 800-56A) -Enhanced logging and debugging capabilities for cryptographic operations - Maintained backward compatibility while upgrading security infrastructure Security improvements: - Cryptographic isolation between different key purposes - Enhanced protection against cross-key attacks - Improved resistance to future key compromise scenarios - Better compliance with OWASP cryptographic storage guidelines Technical details: - Refactored deriveSharedKeys() method for proper HKDF implementation - Updated WebRTC manager to use new messageKey API - Added comprehensive error handling and validation - Improved browser compatibility with standardized cryptographic operations - This update strengthens the existing security foundation with modern cryptographic practices while maintaining full system compatibility.

#### **HKDF Security Properties**
|
||||
- **RFC 5869 Compliance:** Full adherence to HMAC-based Extract-and-Expand Key Derivation Function standard
|
||||
- **Proper Key Separation:** Each derived key uses unique `info` parameter to prevent key reuse
|
||||
- **Salt Security:** 64-byte cryptographically secure salt for each derivation
|
||||
- **Non-Extractable Keys:** All operational keys are hardware-protected and non-exportable
|
||||
- **Forward Secrecy:** Independent key derivation for each session prevents key compromise propagation
|
||||
- **Algorithm Consistency:** SHA-256 hash function for optimal compatibility and performance

### Layer 19: HKDF Key Derivation (RFC 5869 Compliant)
|
||||
**Purpose:** RFC 5869 compliant key derivation with proper key separation and cryptographic security
|
||||
|
||||
**Technical Specifications:**
|
||||
- **Standard:** RFC 5869 HMAC-based Extract-and-Expand Key Derivation Function
|
||||
- **Hash Function:** SHA-256 for optimal compatibility and performance
|
||||
- **Salt Security:** 64-byte cryptographically secure salt for each derivation
|
||||
- **Key Separation:** Unique `info` parameters for each derived key type
|
||||
- **Non-Extractable Keys:** Hardware-protected keys for enhanced security
|
||||
|
||||
**Implementation:**
|
||||
```javascript
|
||||
// HKDF key derivation with proper separation
|
||||
const deriveSharedKeys = async (privateKey, publicKey, salt) => {
|
||||
// Step 1: Pure ECDH derivation
|
||||
const rawKeyMaterial = await crypto.subtle.deriveKey(
|
||||
{ name: 'ECDH', public: publicKey },
|
||||
privateKey,
|
||||
{ name: 'AES-GCM', length: 256 },
|
||||
true, // Extractable for HKDF processing
|
||||
['encrypt', 'decrypt']
|
||||
);
|
||||
|
||||
// Export and import for HKDF
|
||||
const rawKeyData = await crypto.subtle.exportKey('raw', rawKeyMaterial);
|
||||
const rawSharedSecret = await crypto.subtle.importKey(
|
||||
'raw', rawKeyData,
|
||||
{ name: 'HKDF', hash: 'SHA-256' },
|
||||
false, ['deriveKey']
|
||||
);
|
||||

||||

|
||||
const messageKey = await crypto.subtle.deriveKey(
|
||||
{
|
||||
name: 'HKDF',
|
||||
hash: 'SHA-256',
|
||||
salt: saltBytes,
|
||||
info: encoder.encode('message-encryption-v4')
